Use vaccination programme
A before-and-after study in 1980–2005 in a rural area near Rogów, Central Poland (Goszczyński et al. 2008) found that following an anti-rabies vaccination programme, red fox Vulpes vulpes numbers increased. The density of fox tracks was higher after the start of the vaccination programme than before (11.0 vs 5.9 snow tracks/km/day). The same pattern held for fox density as recorded by surveys from vehicles (2.6 vs 1.2 foxes/km2) and for active dens (15.0 vs 9.3 dens with young/year). However, there were fewer cubs/den after vaccination (3.4) than before (3.8). Anti-rabies vaccinations started in 1995-1996. Between 1980 and 2005, fox densities were estimated annually within an 89-km2 area. Estimates were from counts of tracks in snow (average annual transect length was 90 km before and 55 km after the vaccination programme), individuals seen from vehicles in forest habitats, and location of dens and number of cubs within the dens.
